China'scurrentcapacitytotackleclimatechangeisrelativelylowduetoitsrapideconomicdevelopment,hugepopulationandcoal-dominatedenergysystem.Thus,Chinafacesgreatchallengesincopingwithclimatechange,namelytheincreasingpressureofCO2emissionsresultingfromthehighdemandforenergyintheprocessofrapidurbanization,industrialization,andglobalization.Theinter-nationalcommunitynowrequestseachcountrytoputmoreeffortintocontrollingclimatechangesandmitigatingtheirconsequencesinordertocopewithincreasinglyseriousglobalclimatechanges.China'sdomesticneedsanditsglobalclimateresponsibilitiespullthecountryindifferentdirectionsandconfrontChinawithseverepolicychallenges（NDRC2007）.

THEORYANDPRACTICEINTHELOW-CARBONECONOMY

Theideaofalow-carboneconomyisrelatedtothebasicmaterialcyclesonEarth,especiallythecarboncycleandcarbonbalance.Withinagivencarbonbudget,onemaycalculatevariouspublicandcommercialactivitieswithregardtotheircarbonemissions,andusemarketmechanismsfortradingrightsforcarbonemissions,eitherdomesticallyorinternationally,throughmechanismsintheKyotoProtocol.Athoroughreconsiderationofeconomicandsocialactivitieswithregardtothecontrolofgreenhouse（GHG）emissionsmayallowacompletetransformationofthesysteminlinewithlow-carboneconomictheory,andthereforemayprovideasustainablesolutionforglobalclimatechange.Inmanycountries,greatprogresshasbeenmadeinscientificresearchtounderstandtheimpactofhumanactivitiesoncarbonemissionsintermsofinternationalresearchonglobalclimatechanges（Zhao2006）.

Internationalresearchonthelow-carboneconomyiscurrentlyfocusedonthefollowingfourareas:

1）energyconsumption,includingtrans-formingtheenergyconsumptionstructurerelatedandrebuildingenergysystemsintolow-carbonsystems;2）developmentoftheeconomy,concentratingonrelationsbetweenthemodes,stagesanddevelopmentalspeedsofdifferenteconomicactivitiesandcarbonemissions;3）agriculturalproduction,comprisingchangesinlanduse,regulationofagriculturallandandchangesinagriculturalproductionlevelsandstructuretoreduceemissions;4）analysisofeconomicrisksandresearchonvariouscountermeasuresforreductionofcarbonemissions（Zhangetal.2002）.

Besidesrelevantregionalandcomparativeanalyses,moreandmoreimportanceisplacedonintegratedanalysesusingcomprehensivemodelsandlargeamountsofdata,suchascarboncirculation/energymodels,dynamicintegratedevaluationmodelsandenergyconsumptionmodelsforcarbonemissionreduction（Wangetal.2004;Xu’etal.2006）.However,nosatisfactoryprogresshasbeenmadeintheconversionofenergywithintheinternalelementsgeneratingcarbonemissionsandtheinteractionofallelementsinthecarbonemissioncycle（ERI2005）.

Somedevelopedcountriesthathavecomplexenergysecurityconstraintsregardthereductionofgreenhousegasesemissionsasanintegralpartofenergystrategyadjustment.Thesecountriesareattemptingtobuildalow-carbonemissioneconomybyincreasingenergyefficiency,optimizingenergystructuresandstrengtheningR&D.ThestrategypursuedbythesecountriesisinaccordwiththeUNGeneralAssembly'sdeterminationtoinitiateinternationalclimateconventionnegotiations,whichresultedintheKyotoProtocolandtheMontrealClimateChangeConference'sdecisiontostartPost-KyotoProtocolnegotiationsinDecember2005.TheEuropeanUnionhasbeenveryactiveinthisprocess,andinparticulartheUnitedKingdomandGermanyhavemademajorcommitments（Lietal.2006;Xu2007）.

Whilesecuringthesupplyofconventionaldomesticpetroleumenergy,manycountriesareactivelydevelopingrenewableenergyandnewenergysources.Manyarereconsideringnuclearpowerdevelopment,andadjustingandoptimizingtheenergystructuretoeffectivelyreducethevolumeofCO2emittedperunitofconsumption.TheEUhasannouncedthedevelopmentgoalofdevelopingnewrenewableenergysources.TheUSAandJapanhavereinforcedtheroleofnuclearpowerintheirenergystrategies,aftera20-yearhistoryofnotbuildingnewnuclearpowerplants.Japancontinuestoimplementplanstoreinforcethenationalpowersupplywithnuclearpowerandtospeedupitsdevelopmentfrom29%atpresentto30%andupto40%by2030.

CLIMATECHANGECHALLENGESINCHINA

Climatechangeisanoverallglobalconcern,andenergyisthematerialbasisandguaranteeforthesustainablegrowthofChina'seconomy.Chinaisalsooneofthemainemissionsourcesforgreen-housegases.Ontheonehand,Chinacurrentlyhasashortageofenergy,while,ontheotherhand,itconsumestoomuchenergy,whichincreasestheemissionofCO2.Endeavourtocontrolgreen-housegasemissionsandstrengthenitssustainablegrowthcapabilityisbothafulfillmentoftherequirementsoftheUnitedNationsFrameworkConventiononClimateChangeandtheinevitableresultofthefullimplementationofscientificdevelopmentconceptsinthisnewsituation.
